URL.revokeObjectURL() static method releases an existing object URL which was previously created by calling URL.createObjectURL() . Call this method when you've finished using an object URL to let the browser know not to keep the reference to the file any longer.

注意： 此特征可用于 Web 工作者 .

注意： This method is not available from service workers, due to issues with the Blob interface's life cycle and the potential for leaks.
